WINDOW-SCREEN.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed April 24, 1907. Serial No. 370,035-

To all whom it may concern:

Be it known that I, FERDINAND JOHN BOEHL, a citizen of the United States, and resident of Spokane, in the county of Spokane and State of l/Vashington, have invented an Improvement in Window-Screens, of which the following is a specification.

My invention is an improvement in the class of window-screens which are formed of woven wire or wire gauze attached to wooden frames, the construction and arrangement being such that side openings are provided through which flies and other insects may freely escape from a room or apartment, but are prevented from returning.

The invention is embodied in the construction, arrangement, and combination of parts hereinafter described, and illustrated in the accompanying drawing, in which Figure 1 is a face view of a window-screen constructed according to my invention, a portion of the screen proper being cut away for sake of better illustration. Fig. 2 is a side edge view of the screen. Fig. 3 is a transverse section on the line 33 of Fig. 1. Fig. 4 is an enlarged transverse section similar to Fig. 3.

The rectangular wooden frame to which the screen proper is applied, comprises parallel side bars 1 and parallel top and bot tom bars 2 and 2. The bars 1 and 2 are beveled on the outer side, as indicated in Figs. 3, 4, and to such beveled portion is attached a narrow piece or strip 3' of wovenwire, or wire-gauze, the outer edge of the same projecting outward beyond the bevel but not beyond the side of the frame. A piece 4 of wire-gauze having the same form as the frame, is applied to the latter so that its side and top edges extend as far laterally as the narrow strip 3, the supports and spacing devices 5 being arranged between them and secured by nails to the frame. Such devices are beveled on the inner side, while their outer sides are in a plane parallel to the face, or flat side, of the frame. They are made preferably of sheet metal cut and bent to the proper form and provided with holes for receiving the securing nails or screws. The same nails or screws that secure the devices 5 pass also through the narrow strips 3, and thus aid in securing the latter flat upon the bevel of the frame. As indicated in Figs. 2, 3, and 4, the strips 3 and screen 4 are separated at their outer edges by a space wide enough for the passage of flies and various other insects, the inner ends of the spaces being, however, much wider, so that the insects will be induced to crawl along either of the screen parts 3 or 4, and thus led or guided toward the exit. At the same time, the outer edges of the parts 3, 4, are sufliciently near each other and present such rough or ragged edges, that the entrance of insects is efl'ectually prevented. The lower end of the screen 4 is secured by nails to the lower cross bar 2 of the frame, and extends a short distance below the same as indicated in Figs. '1 and 2; The said bar projects from the face of the side bars 1, far enough to hold the lower portion of the screen 4 duly separated from the adjacent portions of the side stri s 3.

T e bevel formed at the outer sides of the bars 1, 2, does not materially weaken the frame, and at the same time provides for attachment and firm support ofthe wire strips 3, While the free side edges of the latter project beyond the bevel so as to permit the passage of light through them, which is important in inducing the flies or other insects to pass out through the lateral openings. The side bars 1 also extend below the bottom bar 2 the same distance as the screen 4. The object of this constructive feature is to allow rain water, or water discharged upon the screen from a hose in washing the windows, to pass down and find free escape under the bottom bar 2 it being understood that the ends of the side bars 1 in practice rest upon the ledge, or sill, of a window.

It will be understood that my invention is applicable to screens for doors as well as windows.

I claim:

1. The combination with a frame having its inner outside edges beveled, and narrow Woven-wire strips secured thereto and their outer edges projecting beyond the bevel, of a woven-wire sheet applied to the frame, and devices interposed between its edges and the aforesaid strips, the outer sides of said devices being in a plane parallel to the frame, whereby lateral escape openings are formed between the edges of the said strips and sheet, said openings being widest at their inner ends, as and for the purpose set forth.

2 The improved screen comprising a rectangular frame having side bars extended below the bottom bar, and a screen secured to the face of the frame and its lower edge provided at the lower corners of the frame extended below the bottom bar, as and for for supporting the bottom bar out of contact 10 the purpose specified. with a ledge, or other part,.upon which the 3. The improved screen comprising a recscreen may rest, substantially as described; 5 tangular frame having woven-wire strips ap- FERDINAND JOHN BOEHL. plied to the side bars, and a woven-wire Witnesses: sheet extending over the whole frame and JOHN SINGLETON LEFOA,

below the bottom bar thereof, means being ERNEST HENRY FENINGER.
